8--4--2--1
----1--0--1
--------1--1
_________
--------1--0
_________
Check
101 = 4 + 1 = 5 (base ten)
11 = 2 + 1 = 3 (base ten)
5 - 3 = 2 (base ten)
2 = 10 (base two)

Take the 2's complement of the subtrahend and add. For example,
96 - 78
1100000 - 1001110
- 1001110 = 0110001 + 1 = 0110010
Perform the addition without the final carry.
1100000
0110010
-------------
0010010 = 18
